....rapidly time varying background, target occlusion and or sudden changes in local or global illumination. Three Dimensional Rigid Body Motion Estimation Researchers in computational vision have been studying the problem of estimating three dimensional motion from a sequence of images, intensively [1, 3, 4, 55]. Although the objects of interest are typically quite large (greater than 80 pixels) there is an extensive body of research in three dimensional rigid body motion estimation [55 58] which assumes the prior existence of a set of feature point correspondences. These algorithms can compute the ....
.... have been studying the problem of estimating three dimensional motion from a sequence of images, intensively [1, 3, 4, 55] Although the objects of interest are typically quite large (greater than 80 pixels) there is an extensive body of research in three dimensional rigid body motion estimation [55 58] which assumes the prior existence of a set of feature point correspondences. These algorithms can compute the three dimensional motion of a rigid body given the location of known feature points in each image of a sequence. The detection and tracking of these feature points is suitable for ....

....This is the case with the recovery of depth from an image spatiotemporal changes; one speaks, here, of a temporal sequence of images or, simply, an image sequence. 3D interpretation from a sparse set of image displacements, or binocular correspondences, has been extensively researched [2,3] and several textbooks have been written on the subject [4 6] # dense interpretation can be obtained via dense estimation of disparity [1,7] or directly without prior estimation of disparity [8,9] In either case, the epipolar constraint affords a major economy of search for an estimate. 3D ....

....the 3 D motion and structure of a rigid object from image sequences is a fundamental problem in applications such as target recognition, reconnaissance, visionbased servoing, and computer graphics. The main approaches to 3 D trajectory estimation have usually exploited either point features [2] or optical flow [3] independently. In feature based approaches, 3 D motion and structure are estimated by observing the 2 D positions of a set of relatively sparse set of image features (corners, lines, regions, etc. over two or more time sequential images. In contrast, optical flow based ....

The second approach is based on 3 D reconstruction by dynamic vision [9] [11] This method uses the displacement of the camera and the 2 D motion computed from the image sequence, but it still does not provide accurate results related to the reconstruction errors. On the other hand, active vision [12] 19] includes strategies to select the motion of the camera to ....

....and important problem in diverse fields such as medical imaging, computer vision, art, entertainment etc. The problem of registering two images, be they 2D or 3D, is equivalent to estimating the motion between them. There are numerous motion estimation algorithms in the computer vision literature [1, 3, 8, 10, 12] that could potentially be applied to the problem of registration of volume images specifically, MR brain scans which is the topic of focus in this paper. We draw upon this large body of literature of motion estimation techniques for problem formulation but develop a new numerical algorithm for ....

A good review of motion estimation is presented by Aggarwal and Nandhakumar [1]. Comparison of different motion estimation techniques are compiled by Dufuax et al. [4] and Hand [6] The book by Konstanides and Bhaskaran [2] provides an excellent treatment on DCT based video compression techniques (for example, H.263, MPEG 1, MPEG 2, etc) Thus we forego the details. 2.1 ....

....and their reliability considering the orientation of the 3D normal vector of the corresponding node in the previous frame. Having a set of 2D feature points at our disposal many are the methods which have been proposed for the computation of the 3D motion parameters (R, T) of the face model [2], and their accuracy in the solution depends highly on the reliability of the given feature correspondences. Having ensured from the previous step that the selected feature correspondences are the best possible for the given tracking method we employ the method proposed in [5] and [6] enhanced to ....

.... salient feature points on the object and establishing correspondences for the key frames, classical structure from motion algorithms can be applied to simultaneously estimate the 3 D positions of feature points as well as the object poses (or the relative camera poses) at the key frames [7]. A triangle mesh of the shape model S is constructed from the feature points, and object poses p nd at the key frames can be used to initialize the process for estimating object motion at every frame as will be described in Section 2.2. Note that in this work, we have selected the feature points ....
